Moving box maze for flashlight fun. This would make a great game during a move when there are plenty of boxes and little else is unpacked.
Quiet time activity -- sponge blocks (would be great for kids who don't sleep at naptime) I think that this can be used as a great building tool in addition to blocks. How creative!
